..riro.
Took a long time to get this online but here we go, the last tramp in NZ:
--------------
Before reporting the actual Northern Circuit walk I have to mention one glorious moment of victory. We spent a couple of nights at a backcountry hut and among other things had a river boat race. Here you can see the winning ship with the stream in the background.

Later along the track we had a couple of rematches with floating rocks. I guess they have everything in NZ.
Morning moods at the hut, which we were lucky enough to have all by ourselves for the second night.

Towards the actual hike and Mt Ngauruhoe:

Mt Ngauruhoe closer:

Climbing begins to the top of the cone:

Up!

Outer ridge of the crater:

Inner crater:

In addition to the clouds you can see steam rising from the mountain:

I recall the discussion went:
-the mountain is steaming.
-no its the clouds, if it was the mountain the steam would be warm.
-it is actually pretty warm.
then saku stuck his hand in
-damn it is actually hot!
So we found out the mountain was active. We got another evidence of that when on the next day we saw the mountain spitting out a black spot..

..which proved to be a rock:

Luckily Saku is a strong guy so he lifted the rock and saved me. Thanks.
A couple of random shots along the way:
Red Crater, the dike was formed when lava pushed up through it:

Blue Lake and Emerald lakes and the hiking track between them:

A wiew from Ketetahi Hut, truly a room with a good view:

Walking into Mordor:

Mt Ruapehu at sunset:

I kinda new that Ngauruhoe and Ruapehu are still active volcanoes but didn't really think about it. After seeing a video of Ngauruhoe's eruption 1975 with 15m lava rocks rolling down, it felt, however, a bit less far away. It also helped to find out that Ruapehu erupted in 1945, 1995, 1996, 2007 and 2009 there was a volcanic earthquake but no proper eruption. Anyway, we didn't see one..blaah. Luckily there's Iceland granting enough smoke for everyone.
